To all whom it may concern:

Be it known that I, WILLY SEOK, of Ober- Ursel, in the Kingdom ofPrussia, German Empire, have invented a new and useful Improvement inGas or Hydrocarbon Motors, (for which I have obtained Letters Patent inEngland, No. 22,834, dated December 31, 1891; in France, No. 218,837,dated January 21, 1892; in Switzerland, (prov.,) No. 4,454, datedDecember 22, 1891; in Austria-Hungary, No. 21,764 and No. 69,503, datedApril 25, 1892; in Spain, No. 13,371, dated May 27,,

1892; in Belgium, No. 99,746, dated May 20, 1892, and in Italy, No.32,903, dated October 31, 1892,)of which the following is aspecification.

My invention relates to an improved construction of a gas-motor, equallyapplicable to hydro-carbon motors, and the object of my invention is toprovide a motor of great simplicity of construction, the working partsof which are so constructed and arranged with relation to each other asto enable their being lodged in a closed casing partially filled withoil, water or other lubricating substance.

By the improved construction hereinafter described, not onlyconsiderable economy of space, but also a complete self-lubrication ofthe working parts are obtained, and, further, the improved motor offersthe great advantage that no injury can be done to the attendant or otherpersons by the working parts, which are all inclosed in the casing, andsaid invention consists in the novel arrangement and combination ofparts hereinafter described and claimed.

In general, the working order of the improved gasor hydro-carbon motoris the same as that of other known constructions; the gas is supplied bya gas feed pipe or by a generator in which hydro-carbon-oil isvaporized; the said gas or vapors are drawn into the machine by thesuction of the piston, which simultaneously draws in atmospheric air;the mixture of gas and air is ignited by a flame and an exhaust valveserves to discharge the products of combustion.

In the accompanying drawings, Figure 1 is a longitudinal, verticalsection of a gas-motor constructed according to my, invention. Fig. 2 isa cross-section drawn to line A-B. O. D. of Fig. 1. Fig. 3 is a detailside elevation illustrating the mechanism for controlling the exhaustvalve, drawn to an enlarged scale. Fig. 4 is a vertical section of thesame drawn at right angles thereto. Fig. 5 is a detail side view of themechanism by which the valve motion is controlledaccording to thevarying positions of the regulator. Fig. 6 is a top view of the same.Fig. 7 is an enlarged detail side view of a part of the same; and Fig. 8represents a gas generator, which however, may be of any knownconstruction destined to replace the gas-inlet-valve, if the motor is tobe worked by hydrocarbon-oil, instead of by gas.

In the drawings a is a closed casing, within which the principal workingparts of the machine are arranged.

b are top-plates secured tothe casing, which plates being removed, giveadmittance to the interior of the casing.

c are journal-boxes to receive the bearings 01 of the shaft-journals e,the bore of said boxes 0 may be slightly tapering according to thetapering shape of the bearings d which, being cut in the direction oftheir length, are forced against each other by the conical bore of thebox 0.

f is the connecting rod mounted on the crank of shaft e, and driving thepiston g within the cylinder h of the machine.

t' is the top-plate of said cylinder and k the valve through which gasand air are drawn into the cylinder h by the suction of piston g. Inhydrocarbon-motors the said valve is is replaced by a suitable gasgenerator, such as shown in Fig. 8, for supplying hydro-carbon vaporsand air to the cylinder h.

Zis theigniting-pipe and m the lamp for heating the same, n the valvefor the exhaust of the products of combustion, 0 the valverod, p aspring tending to close the valve 'n, q an extension of the valve-rod 0,serving to open the valve at suitable intervals, under the command ofthe regulator, as hereinafter described.

r',r ,'r ,r are four gear wheels for the command of the valve, saidwheels being shown in a larger scale in Figs. 3 and 4.

s is the regulator of the machine, 25 a disk or wheel with a circulargroove in the periphery thereof, said disk varying its positionaccording to that of the governor s.

to, 11?, u are a set of connecting rods which transmit motion from thedisk 25 to the parts which command the exhaust-valve n, as more fullyrepresented in Figs. 5, 6 and 7.

The exhaust-valve n, is under control of a cam 11 secured to or integralwith a gear wheel r loosely mounted on the shaft 6 at the side ofanother gear wheel 7-, mounted fixedly thereto. Said wheel 0* gears intoa gear wheel 7' loosely mounted on a fixed trunnion of the machine, andto the said wheel r another wheel r is cast or secured, meshing with theloose wheel 4' on the journal 6. The size of the Wheels 1", r r T is socalculated that 0' makes one revolution, while the wheel 7" fast on theshaft e makes two. To the said wheel 1- a disk or sheave o is cast orsecured, can rying the main cam w, Figs. 3 and 4, and an auxiliary camw. The main cam w serves to operate on the exhaust-valve 12 while theauxiliary cam 00 is provided to lift the said exhaustvalve only when themotor is started to permit the escape of part of the compressed gas andair. The said cams w and ac revolving with the wheel 0 have a bearin gagainst a sheave carried by the extension q of the valve'rod o. The saidsheave y is capable of being shifted on its stem by means of a fork 2,as shown in Fig. 3, and, according to the position of said sheave y, itwill be struck either by the cam 10 alone, or by both cams w and wduring one revolution of the wheel r and disk 1:. If both cams strikethe sheave y, the exhaust-valve n will be lifted twice during onerevolution of the wheel 1' and part of the compressed gas is permittedto escape before being exploded. The lift of the valve n is furtherunder control of the governor .9 through the medium of the disk 25 andconnecting-rods a, n 10", the controlling device acting in the followingmanner: u and n are double-armed levers turning on suitable pivots andconnected by the rod 10 The free end of the lever or rod to engages by apin or anti-friction-roller into the groove of the diskt of thegovernor, causing the other arm of said lever 11/ to swing in thedirection opposite to that in which the disk t is shifted by thegovernor s. The rod 1& transmits the corresponding motion to the lever11, the free end of which carries an inclined surface, which, whenbearing against the pawl u, forces the same into engagement with a notchformed or secured to the rod q, whereby said rod is prevented from beinglowered by the pressure of the spring 0, and, as long as the said pawl11, continues in engagement with the said notch u the exhaustvalue 72 iskept open and the downward throw of piston g performs no drawing in ofgas and air till the said valve 01. is closed again. Owing to the powerstored in the fly-wheel on the shaft e, the piston g will continue towork in the cylinder it till the speed or revolution has diminished sofar'as to allow the governor s to return into its normal position,thereby shifting the disk 15 and levers u and u into the oppositedirection and throwing the inclined face on the lever u out ofengagement with the pawl u. The said pawl being free, is drawn out ofengagement of the notch u by a spring, and the rods q, and 0 are free tobe forced down by the spring 10 whereby the valve n is closed and thepiston 9 draws into the cylinder a fresh quantity of gas and air forbeing exploded.
